（anyone）with a good command of English 这里的anyone是回答what kind of people的,即We need anyone with a good command of English (anyone是need的宾语,后面的介词短语with a good command of English 作定语...whoever with。。怎么不对？是缺少成分吗？whoever 不能单独使用，只能引导从句。即它不能单独来回答what kind of people其实whoever =anyone who ,，我们把with a good command of English 改为has a good command of English就可选whoever了has with 有什么区别has与with这里都是拥有。。。但是has作定语从句who has a good command of English 的谓语而with只能构成介词短语，不能放在whoever后作定语，更不是谓语。又如 China is a country with a long history= China is a country which has a long history
